Question

Q.6) A student places a pile of coins on a table, as shown in Fig. 6.1. There are 8 coins in the pile. The weight of each coin is 0.036 N. The area of each coin is 0.0013 m². Calculate the pressure on the table caused by the pile of coins ? Fig. 6.1. [3] Pressure​

Answer 1

Answer:

221.5Pa

Explanation:

given,

weight of one coin = 0.036N

no:of coins = 8

base area of each coin = 0.0013m²

Force on table = total weight of coins

                         = 8 × weight of each coin

                         = 8 × 0.036 = 0.288N

pressure = (force exerted)/(area)

               = (0.288)/(0.0013)

               ≅ 221.5 Pa
